Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Percentage change of mineral content in the dental enamel after an observation period of four weeks. The alteration of the fluorescence of the enamel is determined by QLF (quantitative light-induced fluorescence). The fluorescence is proportional to the mineral content of the enamel. | — |
Secondary
| Measure | Time frame |
|---|---|
| Percentage change of surface roughness of the dental enamel (sa-value) adjacent to the bracket after an observation period of four weeks. Demineralization enhances, remineralization reduces the surface roughness.The determination of the sa-value is performed by focus variation microscopy (FVM). | — |
